Divers responded and recovered the body of a man inside the plane, officials said. Police later identified the man as 51-year-old Ricardo Laporta Barboza, from Coral Gables.

"The guy just plummetted straight in, no deviation in the motor, no fluttering of the wings, it was like he was a kamikaze war pilot going straight down," witness Tom Romanowski said. "It happened so fast that I mean actually, we blinked sitting in the water, looking around, we never saw it coming and straight down, straight into the water."

Homicide investigators are investigating the death and the National Transportation Safety Board is investigating the crash.
